RFID smart vehicle management system background
With the development of the economy and the improvement of people’s living standards, there are more and more private cars. For parking managers, vehicle management is getting more and more difficult. During the rush hour, parking the car in the parking lot takes a long time to line up, and the administrator has to issue stop signs one by one. These procedures are relatively time-consuming. For the public parking lot, some trouble is saved, but if there are foreign vehicles entering, it will be more troublesome for the administrator to inquire, and it is difficult to distinguish whether the incoming vehicle is a foreign vehicle. In addition, if there are vehicles coming in, the administrator has to control the entrance gates one by one to let the vehicles come in, which will undoubtedly increase the time of entry. So what method can be used to manage vehicles to make the management more efficient and convenient? This is a headache for parking lot managers.
For this reason, Chuangyi Technology has developed a set of RFID smart vehicle management system from the perspective of customers, with its own advanced technology and excellent development team, in accordance with the actual situation.
The vehicle management system reduces the parking time, saves a lot of trouble for the parking lot administrator, and improves the unified management efficiency of the municipal government’s vehicles. In the long run, it reduces the municipal government’s economic expenditure on vehicle management.
Vehicle management business requirements
When the vehicle passes through the turnstile, the driver has to complete a series of actions, such as: “slow down”, “stop”, “open the window”, “swipe the card”, “wait for the lever to lift”, “drive”, etc. Obviously , This is an inefficient management method that can complete access management functions. For a long time, parking lot managers have hoped to find an efficient way to manage driving vehicles without stopping. Such a problem-solving method can satisfy both the driver and the parking lot manager. It also involves issues related to vehicle theft prevention and foreign vehicle identification.
Advantages of RFID smart vehicle management system
Remote recognition
The effective reading distance between the card reader and the label on the license plate is 0 to 80 meters, which gives a time buffer from the card reader recognition to the opening of the automatic gate. This distance is suitable for most parking environments , This distance is also the technical basis for “passing customs without stopping”;
Automatic recognition of vehicles in the hospital
For the vehicles in the hospital, the system can automatically identify, automatically release the gate, and automatically allocate parking spaces. The system saves the basic information of the vehicles in the hospital. The database records the license plates, owners, entry and exit information of the vehicles in the hospital and so on. When passing through the entrance, the card reader at the entrance recognizes the tag information, and the system controls the car’s license plate to scan and take a photo. Then the license plate number is extracted and compared with the license plate in the system database. If it is a vehicle in the courtyard, The system controls the automatic opening of the brakes;
Out-of-hospital vehicle recognition
For vehicles that are not in the hospital, car owners can obtain parking spaces in two ways, either by picking up the card or swiping the card through the mobile phone. The car host’s mobile phone is swiped at the “mobile phone swiping point” at the entrance, or a card for a temporary parking space is picked up at the card pick-up point. The car is released and the parking space is automatically allocated. For the mobile card swiping method, the parking space will be bound to the mobile card, and the owner’s mobile phone will receive information when the car drives away, preventing non-owners from driving away;
The brakes open automatically
The card reader recognizes the license plate. If the license plate shows that it is in the courtyard, the system will control the brakes to open automatically, eliminating the need for the administrator to open the brakes for each vehicle. This saves time and saves the administrator. Less trouble; for the vehicles in the hospital, the system can display whether they are in the hospital. When the vehicle enters the yard, the system shows that the location of the vehicle is in the yard; the card reader at the exit reads the vehicle’s exit information, and the system displays the location of the vehicle as not in the yard. Using this principle, the vehicles in the hospital can be counted, and then based on the data in the database, it can be judged at any time whether the vehicle is in the hospital and who belongs to it, so as to play a role in preventing theft to a certain extent;
Long use time
The electronic label has a long working time and can work continuously for 6 to 8 years without maintenance during the period. This reduces maintenance costs and directly improves economic benefits.
Introduction to RFID Smart Vehicle Management System
Overview of RFID vehicle management
Based on its own mastery of RFID technology and full understanding of the vehicle management business process, Chuangyi Technology applies RFID technology to the vehicle intelligent parking lot management process, thereby solving the traditional vehicle release method of parking and swiping cards, and greatly improving the efficiency of vehicle release , To ensure smooth traffic at the entrance and exit of the parking lot. Through correct design and installation, vehicles can pass without stopping on multiple lanes at the same time without interfering with each other.
In our solution, there are mainly the following key technologies: electronic tags (long-distance cards), long-distance readers and other key equipment.
For internal vehicles, as long as the label of Chuangyi Technology is placed behind the license plate of the vehicle, the management system can effectively and accurately collect and record the vehicle information entering and exiting the unit in a large range and upload and process it as needed. The background computer According to the uploaded information, identify the attributes of the vehicle and drive the gates to open correctly to ensure that the access control system has the ability to efficiently release and achieve “pass without stopping.” After the system recognizes that it is an internal vehicle, the car’s license plate number is displayed on the display at the door, the system allocates free parking spaces, and sends a sound to tell the owner of the parking space number. A card reader is installed in the parking space. At this time, the card reader of the allocated parking space recognizes the electronic tag. If another car parks in the parking space, the card reader will send out an alarm.
For external vehicles, the system will automatically allocate parking spaces regardless of whether it is swiping a card with a mobile phone or receiving a card. The difference is that the mobile phone swipe card can be bound to the card reader on the parking space, and the principle and process are similar to those of the internal car. The car that picks up the card can only be parked in a temporary parking space.
The installation method is very simple, as long as the reader is fixed to the appropriate position of the entrance, for example, on the wall or bracket. The reader and the background management system (software) are connected through a standard interface, the standard interface includes: RS232, RS485, etc. The electronic tag is installed on the vehicle as its identification. The card reader reads the data of the electronic tag (such as vehicle information, vehicle entry and exit time, etc.) and transmits it to the computer, thereby realizing non-stop management. The card reader of the parking space is installed on the parking space.
RFID vehicle management process
Interior car
An electronic tag is installed behind the license plate of the internal vehicle, which identifies the vehicle. A fixed card reader is installed at the entrance of the parking lot, which can identify electronic tag data within a certain range. If the card reader reads the tag and determines that the tag belongs to the hospital, the license plate number and parking space of the car will be displayed on the screen at the entrance. At this time, the gate at the entrance is automatically opened and the vehicle owner can go directly to the parking lot to find the corresponding parking space. A fixed card reader is installed in the parking space. After the system allocates the parking space, the card reader recognizes the tag of the car. If it recognizes that the wrong car is parked in the parking space, the card reader will sound an alarm;
When the car leaves, the car passes through the exit, the card reader at the exit recognizes the tag, and the gate opens automatically, and then the card reader sends a signal to the system center to clear the parking space information in the system database, and the parking space is idle;
Outside car
Since external vehicles are not equipped with electronic tags, two methods are provided: one is to swipe the card with a mobile phone; the other is to take the card. For the mobile phone swipe method, the car owner swipes the mobile phone card in the mobile phone swiping area (the mobile phone card is an RFID-sim card). After the system reads the information, it allocates an idle parking space to the car. At this time, the mobile phone card and the parking space begin to bind Certainly. The parking space number of the car is displayed on the screen, and the subsequent process is the same as that of the internal car. With regard to the way of picking up the card, after the car owner picks up the parking card, the system will automatically allocate an idle temporary parking space for the car. The owner parks according to the allocated parking space. When leaving, the car owner handed in the card at the exit, and the gate at the exit was opened at this time.
